[0001] The utility model relates to the technical field of computerized flat knitting machines, in particular to a novel mesh measuring mechanism. Background Art

[0002] The mesh cam of a flat knitting machine is a core component in the machine head. When knitting garment pieces, some pressing plates need to switch actions, and the knitting cam and the needle transfer cam need to make corresponding actions. It is necessary to have auxiliary mechanical devices and rely on magnet control or other electronic control devices to form a set of complex cam devices, among which the mesh cam must be used. The existing mesh cam is simple in shape, basically a straight quadrilateral or a quadrilateral with rounded corners. However, the mesh cam of this structure, the heel of the long needle will inevitably rub against the surface of the mesh cam under the action of elasticity. The heel of the long needle or the mesh cam is prone to wear after long-term work, and when the mesh cam is lowered, it is easy to collide with the knitting needle, which greatly increases the failure rate of the mountain plate and increases the maintenance cost. Utility Model Content

[0008] Furthermore, the outer wall of the flange is provided with a guiding slope, so that the upper butt of the spring pin in the A-position needle track moves along the lower edge track of the return stitch triangle under the guidance of the guiding slope.

[0009] Furthermore, a slide groove is provided on the mountain plate, a slider is slidably arranged in the slide groove, the mesh triangle is fixedly connected to the slider, and a mounting plate is fixedly arranged on the rear side of the slider, and the slider is driven by a rotating driving device to drive the mesh triangle to slide along the slide groove.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Figure 3 It is a schematic diagram of the structure of the convex piece. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Reference Figure 1As shown, a novel mesh mechanism includes a mesh cam 1, which is a pair and slidably arranged on both sides of a dish mountain 3 of a mountain plate 2. The dish mountain 3 is an existing structure, and this embodiment is not repeated here. A slide groove 21 is provided on the mountain plate 2, and a slider 211 is slidably arranged in the slide groove 21. The mesh cam 1 is fixedly connected to the slider 211, and a mounting plate is fixedly arranged on the rear side of the slider 211, so that the mesh cam 1 can move up and down along the slide groove 21, and a rotating drive device is fixedly installed on the rear side of the mountain plate 2. In this embodiment, the rotating drive device preferably adopts a servo motor, and its output shaft is transmission-connected with the mounting plate. The connection method between the rotating drive device and the mesh cam 1 can refer to a novel mountain plate device, a knitting needle assembly and a knitting method of a computer flat knitting machine with a publication number of CN118854536A. This embodiment is not repeated here, so that the slider 211 is driven by the rotating drive device to drive the mesh cam 1 to slide along the slide groove 21, so as to adjust the tightness of the fabric.

[0017] Combination Figure 2 As shown, further, an avoidance groove 11 is provided on the lower end face of the mesh triangle 1, a plane portion 111 is provided in the middle of the avoidance groove 11, a first guide slope 112 is provided between one side of the plane portion 111 and the side wall of the mesh triangle 1, and a second guide slope 113 is provided between the other side of the plane portion 111 and the side wall of the avoidance groove 11. In this embodiment, the heights of the first guide slope 112, the plane portion 111 and the second guide slope 113 gradually decrease in sequence. Since the surface of the traditional mesh triangle is a whole plane, when the heel of the long needle is pressed into the needle groove and enters the surface of the mesh triangle along the surface of the disc mountain, the heel of the long needle will inevitably rub against the surface of the mesh triangle under the action of elasticity, and the heel of the long needle is prone to wear after long-term work.

[0018] Compared with the existing mesh cam, when the long needle of the present embodiment enters the surface of the mesh cam 1, due to the height difference between the first guide bevel 112, the plane portion 111 and the second guide bevel 113, the heel of the long needle gradually releases the elastic force, thereby reducing the friction of the long needle and alleviating the friction between the heel of the long needle and the surface of the mesh cam, thereby greatly improving the service life of the mesh cam and the long needle and reducing the production cost.

[0019] Furthermore, a step surface 12 is provided between the upper parts of the plane portion 111, the first guide slope 112, the second guide slope 113 and the surface of the mesh triangle 1, so that the step surface 12 is utilized to limit the long needle to prevent the long needle from moving upward and causing needle deviation.

[0020] A plane edge 13 which is in the same horizontal plane as the mesh triangle 1 is arranged on the side of the avoidance groove 11 facing the disc mountain, and the first guide slope 112 is connected with the plane edge 13 on the side away from the plane portion 111, thereby increasing the strength of the edge of the mesh triangle 1, avoiding the edge of the first guide slope 112 of the mesh triangle 1 from being worn or broken under continuous impact due to long-term friction between the edge of the first guide slope 112 of the mesh triangle 1 and the heel of the long needle, thereby greatly improving the service life of the mesh triangle.

[0021] The bottom edge of the avoidance groove 11 has a rib 14 connected to the plane edge 13, and a slope surface 141 is provided between the rib 14 and the plane portion 111 and the first guide slope 112, thereby further increasing the thickness of the rib 14, greatly increasing the strength of the rib 14, and also avoiding the wear of the rib 14 due to the long-term friction of the heel of the long needle, thereby effectively improving the service life of the mesh triangle.

[0022] Reference Figure 1 , Figure 3 As shown, there is a protrusion 15 on one side of the lower part of the mesh triangle 1, and one side of the protrusion 15 abuts against the side wall of the disc mountain 3, and a flange 151 is provided on the side of the protrusion 15 abutting against the disc mountain 3, so that a needle moving channel 152 is formed between the flange 151 and the side wall of the mesh triangle 1, and the outer wall of the flange 151 is provided with a guiding slope 153. When the rotary drive device fails and the mesh triangle drops to the lowest position, the upper heel of the spring pin in the A-position needle track 4 moves along the lower edge track of the return needle triangle under the guidance of the guiding slope 153, preventing the upper heel of the spring pin from colliding with the mesh triangle, avoiding damage to the spring pin or the mesh triangle, thereby reducing maintenance costs.

They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
